            {{event.tutorialName}}
        </ng-template>
    </p-timeline>
</div>

• app.component.ts:

Javascript

import { Component } from "@angular/core";

@Component({
    selector: "app-root",

export class AppComponent {
    gfgCourses: any[] = [];

    ngOnInit() {
        this.gfgCourses = [
            {
                tutorialName: "DSA Self Paced"
            },
            {
